Biography
Norimasa Yamanouchi was born in the Kanto Region, to the Yamanouchi branch of the Uesugi clan. He was the adoptive father of Kenshin Uesugi, his vassal who controlled the Nagao Uesugi clan. He aided him in the rebellin against Harukage Uesugi, slaying him to assist the Uesugi in a rebellion. He became a loyal ally of the Nagao, and he assisted the Ogigayatsu Uesugi in the 1545 Siege of Kawagoe Castle, where the Ogigayatsu clan was ruined, leading to their defeat in 1546 at the Siege of Edo Castle. In 1548, the Hojo clan took Tochigi Castle from the Yamanouchi, led by Mitsuzumi Ijuin, but made peace with Norimasa shortly afterwards. In 1554-1558, he fought against the Hojo to retake the Kanto alongside Kenshin, who withdrew after the castle was theirs for the taking. Norimasa ruled over the castle for a while, but eventually was killed in battle with the clan.
